From a story on washingtonexaminer.com by Tevi Troy headlined “Barking at the Press”:

The official transcript of President Joe Biden’s recent presser will make for an interesting historical document. “Do you think,” Fox’s Peter Doocy asked as the event broke up, “inflation is a political liability ahead of the midterms?” “No, it’s a great asset,” Biden responded sarcastically, clearly annoyed by the (rather tame) question. “More inflation. What a stupid son of a b****.” That last part Biden muttered under his breath, but nothing is under your breath when said in front of a microphone. Perhaps in a nod to transparency, the official White House transcript includes the exchange, including the insult, in full.
